Application filed July 7,

The object of this invention is to control or operate the registering and printing mechanism of a liquid dispensing pump of the type disclosed in U. S. application for patent, Serial No. 71,804, filed November 27, 1925,that disclosure including means for making a printed record of the number of gallons of liquid dispensed, so that the owner or other individual in authority, may be informed at all times regarding the sales made,-and the disclosure in that application further including means for preventing the operation of the pump Without automatically producing a record of the kind indicated.

A further object of the n'esent invention s to make it possible to control the device by the weight of the nozzl of the discharge d ct, including a section of the latter, the

removal of the nozzle from the particular be described, setting supporting element to free or placing in service, the operative elements of the recording device.

Viith the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illutrated and claimed, it being understood inat modifications may be made iii in the scope of 13 claims Without deng from the spirit of the invention.

The pump is now inoperative until the hose is taken down for dispensing gasoline or the like.

The automatic control here disclosed takes the place of the manual control thru the handle employed in the structure described in the application for patent above referred to. The operation of the apparatus will be referred to briefly as follows Then the hose is suspended from arm 13, member 7 is in obstructing relation to some vital element of the pump, this element being released by the removal of the hose. When so removed and shaft 5 rocks under spring action, the roller 10 carried by the arm 9 fixed on shaft 8, comes into engagement with the end 66 on the arm 65 resulting in swinging movement of the latter, so that roller 67 will come into engagement with ribbon 68, forcing the latter into engagement with the paper strip 24.

As the pump is operated, and as every gallon or other unit is dispensed thereby, the plunger 54 will be operated, so that the movement of the actuating element of the pump device will be imparted to the angle lever 49. The result is that at every movement, up and down, of the lever 49, the rod 46 carrying the actuating pawl 4-5 will cause the latter to engage the ratchet wheel 44 on the axis of the printing wheel 33 and move it one step. The parts are so timed that as each gallon, or other unit, is pumped, the element 33 and printing wheel 34: will be moved one step, the retaining pawl 57 acting to prevent retrograde movement.

The number of gallons or other units pumped by the mechanism with which the device is associated, will be indicated by the type face on the printing wheel 33. After the transaction has been completed, it is intended to swing the lever arm 13 to the horizontal position of Figure 1. hen this is done the roller 10 carried by the arm 9 will an operative engage against the trip arm or finger (36 of thecam member 65 and swing the latter so that the roller 67 carried thereby will travel along the ribbon 68 and force it into actual engagement with the paper strip 24- and the type wheel so that a printed record will be made.

Arm 63 engaged by cam 12 will move arm 60 thereof upwardly into engagement'with the roller 59, so that the retaining pawl 58 will be lifted out of engagement with the ratchet 44L, permittingthe element 33 to be returned to normal position. By this means the entire mechanism is reset for the next printing operation at the time the next transaction or sale of gasoline or other liquid occurs. At each printing operation it is of course apparent that the number of gallons will be printed upon the paper strip 24.

Having described the invention what is claimed is 1. In a controlling device for dispensing and recording mechanism, means for obstructing the dispensing mechanism, a shaft mounting said means, an arm rigid with reference to the shaft, a U-shaped frame rotatable with reference to the arm, a spring connected with the frame and with the arm, and means for limiting the movement of the frame.

2. In a device of the class described, a shaft for operating the printing mechanism of a recording device, an arm rigid with reference to the shaft, a U-shaped frame carried by the arm, the frame including elements deflected toward each other to form engaging edge portions, said frame having rotatable. movement, and a resilientdevice for determining the position of the frame, when free to rotate with reference to the arm.

in testimony whereof I aflix my signature.
